The continuous sandwich panel machine mainly consists of the following key parts:

• Feeding system: including metal coil unwinding machine, leveling machine, and feeding device, ensuring that raw materials enter the production line smoothly and continuously.
  

• Forming unit: composed of multiple sets of rolling rolls, it continuously rolls the metal coil into the desired plate profile.
  

• Foaming system: used for injecting and foaming curing the core material of polyurethane (PU) or polyisocyanurate (PIR) sandwich panels.
  

• Composite system: firmly bond the upper and lower metal panels with the core material under high pressure.
  

• Cutting system: equipped with high-precision flying saws or laser cutting equipment to achieve fixed length cutting of sheets.
  

• Stacking and packaging system: Automatically complete the stacking and packaging of finished boards.

The continuous sandwich panel production machine integrates multiple advanced technologies:

• Intelligent control system: using PLC and industrial computer control to achieve precise adjustment of production parameters and process monitoring.
  

• Energy saving design: The heat recovery system can reduce energy consumption, and the closed-loop foaming technology reduces raw material waste.
  

• Flexible production: Rapid mold changing technology enables the same production line to produce sandwich panels of different thicknesses, widths, and panel types.
  

• Online testing: equipped with thickness detectors, density monitoring systems, and surface quality testing devices to ensure product consistency.
  

• IoT integration: supports remote monitoring and data analysis, enabling predictive maintenance and production optimization.

The products produced by continuous sandwich panel making machines are widely used in:

• Industrial plant and warehouse buildings
  

• Cold storage and cold chain facilities
  

• Cleanrooms and Hospital Buildings
  

• External walls and roofs of commercial buildings
  

• Modular building components

Advantages of continuous sandwich panel manufacturing machine:

• High production efficiency, up to 15-20 meters per minute
  

• Stable product quality and high dimensional accuracy
  

• Can produce ultra long sheets (up to 16 meters in length)
  

• High material utilization rate and less scrap material
  

• Adapt to various combinations of core materials and panels
